Which type of erosion is characterized as the 'wearing away' of the river bed and banks caused by the river's load?
Understand the Problem
The question asks to identify the type of river erosion where the river's load (sediment) causes the 'wearing away' of the river bed and banks. Understanding the definitions of each type of erosion (hydraulic action, solution, attrition, and corrasion) is needed to select the correct answer.
Answer
Abrasion, also known as corrasion, is the wearing away of a river bed and banks caused by its load.
The type of erosion characterized as the 'wearing away' of a river bed and banks by its load is called abrasion, also known as corrasion.
Answer for screen readers
The type of erosion characterized as the 'wearing away' of a river bed and banks by its load is called abrasion, also known as corrasion.
More Information
Abrasion (or corrasion) is one of the four main types of river erosion, alongside hydraulic action, attrition, and solution (corrosion). It is a significant factor in shaping river channels and landscapes.
Tips
A common mistake is confusing abrasion with other types of erosion like attrition or hydraulic action. Abrasion specifically involves the wearing away by the river's load.
